3 Claims.

This invention relates to a self-adjusting sump pipe, and it has particular reference to the provision of a simple and inexpensive slotted pipe or cylinder of fairly large diameter which may be utilized as a sump, trap, or the like, in a drain line.

In laying sewers and drain pipes, it is frequently necessary to provide a receiver, positioned Vertically, into which the sloping drain pipe discharges. A typical example occurs in the cellars of buildings where it is desired to make provision for draining the floor, and to safeguard the public sewerage from entry of excessive amounts of dirt or large objects tending to clog the lines. Heretofore, this condition has been met by installing the drain lines in such manner that they adapted themselves to whatever conventional type of trap or sump the builder or plumber happened to have available, with the result that much time has been consumed in making the fittings, or unsatisfactory results have been obtained because the conventional trap, when installed, required changing the drain pitch from its most satisfactory inclination. It also frequently happens that valved or sectioned conventional traps are too complicated for the job which they are called upon to do, inasmuch as a simpler device would be equally effective and also less expensive.

The present invention provides a drain receiver, which may be employed as a sump, simple trap, or well for a pump, which is inexpensive and which may be set at the desired level to accommodate the drain pipes when laid at their correct pitch.

One form of the invention is illustrated in the accompanying drawing, wherein:

Fig. 1 is a perspective of the receiver; and

Fig. 2 is a vertical section taken along the line 22 of Fig. 1, and also indicating the location of drain pipes.

The receiver consists generally of a cylinder ll having an open end l2 and an end I3 which may be open, or solid as shown, the solid end prefer-.

ably being formed with a central section M of reduced thickness. Embedded in the wall of the cylinder II is a reinforcing mesh or wire screen I5 which may extend entirely around the cylinder and lengthwise thereof for such distance as may be desired. The cylinder wall is also formed with one or more longitudinally extending slots I6, I1, extending about half way from the open end [2, and which are spanned as shown in Fig. 1 by the mesh 15.

For installation in a residence of medium size, as for example in the cellar or in the floor of an adjoining garage, the receiver ll may be about two feet long and about fifteen to twenty inches in diameter, while the slots l6 and I! may be about six inches or more wide, to receive drain tile of the usual diameters. For other installations and applications, the dimensions may be varied accordingly. The receiver may be readily made from concrete poured into a form, or from clay which is later burned to provide a vitrified tile type of unit. When the latter is adopted, it is less important to extend the mesh l5 entirely around the cylinder.

In use, and'following the example previously referred to, it may be assumed that the pipe I8 represents the discharge end of the drain and that this pipe has been laid at a pitch suited to the particular installation. If the broken line 19 is taken to indicate the fioor level, then the earth is simply excavated at the end of the pipe l8 to the depth of the receiver, which is then dropped into place with a slot in line with the pipe end. The pipe l8 will then abut the mesh I5 over some area between the open end l2 and the lower end of the slot, and the workman can mark this With a suitable instrument. The mesh I5 is then cut away, if desired, so that, upon again positioning the receiver, the end of the pipe I 8 projects slightly into the cavity of the cylinder II.

It will be seen that with this construction, the receiver is self-adjusting with respect to the drains, and that it can be readily fitted in the field into proper position with respect to both the floor elevation and the drain pitch without extended labor or relocation of the entire pipe system. The length of the slot permits vertical adjustment at the site to any desired elevation within practical limits, while the width of the slot is made sufiicient to accommodate drain pipes of the usual diameters.

In Fig. 2, there is also shown another pipe 2! positioned in the slot l1, and also taking its own elevation with respect to the slot in the manner just described. This pipe may be regarded as a connecting line to the public sewerage. Alternatively, or concurrently in some instances, another connection may be made by knocking out the weak bottom portion M to provide an opening for another drain line 22, or for seepage to the earth below. It will also be obvious without illustration that the suction pipe of a sump pump may also enter the receiver through its top, and that bafiies or partitions may be installed on the job, if desired, to qualify the receiver the better as a sludge trap.

After the receiver has been installed, the open portions of the mesh l5 may, if desired, be sealed by using the mesh as a supporting grid for cement, or other plastic material, which is simply molded into place over the wire to provide thereby a substantially unbroken exterior surface.

It will be seen that the receiver of the present invention is readily applicable to a Wide variety of plumbing problems which otherwise would have to be solved by specially designd fittingsem tailing increased initial cost for materials as well as additional labor charges. In the specific embodiment of the invention herein-illustrated, the slots l6 and I! are shown as being diametrically opposed, but it should 'be understodd that the invention is not limited to-this preciseconstruction. The invention is=further-susceptible of other variations without sacrificing its advantages of economy and universal adjii'stability, and therefore it is desired that the scope of the invention be deemed "commensurate *with "the context of the following claims.

I- claim: =1. A hydraulic receiver adapted to be installed transversely of a 'drain'plpe comprising a ceramic wherein 'the Wall of the byl'lri'der is provlii'ed w'ith -35 4 a plurality of slots extending longitudinally from the open end, each of said slots being covered with wire mesh embedded in the wall of the cylinder.

3. A hydraulic receiver adapted to be positioned transversely of an inclined drain pipe to receive the discharge from such pipe comprising a ceramic cylinder having an open end, slots extending from said open end-through the wall of 10 'the cyliri'der -ahd lengthwise therof -for at least twice the width of the slot, the width of the slot being such as to receive the end of drain tile having an outside diameter of six inches, whereby the receiver may be adjusted vertically with respect t said drain-pipe when said pipe is fixed as 170 "pitch'and elevation, a wire mesh screen -embedded-in the wall of the cylinder and covering the area of said slots, said screen reinforcing the cyl irider and providing a support for said tile and for plastic sealing material applied thereto "on the slte of installation.
